USB Thumb-Drive || Other Flash Memory
I'm looking for a cheap and easy way to connect some kind of flash memory to a BS2 to allow the storage and retrieval of information in text files.
Basically, I want the stamp to read/write text files to some kind of flash memory that can then be removed and read/written to by computer. I know there is the USB data-logger, which would work fine, but it's a bit too high price for what I need to do - I need to shave off cost wherever I can.
The flash memory doesn't have to be a thumb-drive, it could be a memory card or somesuch, as long as it can be read & written to by a computer. It also doesn't have to have a lot of storage space. i.e. less than a megabyte would be okay, but more than that is okay too; the amount of space available isn't that important.
Any ideas?
Thanks in advance.

You could attach several EEPROMs to a pair of Stamp I/O pins. Atmel and Microchip have standard EEPROMs with 128K byte capacity and you can put 4 of them on one pair of I/O pins for a total of 512K. There's no interface for the PC end of things, but you could use another Stamp there as an interface. There's no file system for the EEPROM, but it would be easy enough to set something up that would work for your simple task.
The cheapest solution is to get Parallax's datalogger.
I did find that DigiKey has the Vinculum VDrive2 for $25 in single quantities. This is equivalent to the Parallax memory stick datalogger.
